T0 all whom t may concern,

Be it .known that l, CHARLESy H Picann,

, citizen of the United States, residing in the city and county of San Francisco` and State of California, have invented new and useful improvements in Oil Burners, of which the following isa specification` rIhis linvention relates to an oil burner construction. c i

lt is the principalobject of the present invention to provide improvements in oil burners, wherebyfamore efliciently operatingburnermaybe produced of a construcftionwhich is decidedly simple and inexpensive and will insure that oil and steamfmay be suitably mixed to produce proper va` porization andv a resultant thorough combustion.

l The present ,invention contemplates the use of a main casting within which are cast oil` and steam passageways, said passagewaysA .beingl in communication with longitudinal conduits which deliver the oil and the steam to a. vaporizingchamber and to aburner jet.

4The inventiony is` illustrated by way of example in the accompanying.drawings in l which: Fig.` r1 is a View inside elevation showing'one form oi the burner `with `parts broken away to more clearly disclose the passageways providing the steamwand oil.

Fig. 2 is `an enlarged-fragmentary `vertical section `showing another form oit` the invention especially adapted for furnaces. Fig. 3 is a viewin central verticalfsection "showing` another iorm ofthe valve.

"In the drawings 10 indicates an oil-supplypipe here shown as fitted with'a valve This valve is provided with rotated and adjusted b vmeans of a handy /wheel 18.

formed with a bifurcated valve member 141.

' Thevalvemember is cylindrical when its outerwcontour is fitted and has a V-,shape` groove `15 through which the oil may pass fromthe pipe 4l() and into a pipe 16, the

pipe 16 stands vertical and is connected by a union 17 with a burner 18.`This casting `steam pass'agevvayl 20 by means of ,anpinter- The end of the valvevstem f mediate partition wall 21. An oil opening 22 is formed through the partition wall near its upper end and is adapted to be closed or partially closed by ymeans of a tapered vaive member 23. This valve member is carried on the end of an adjustable stem 24- which extends through a stuffing gland 25. The outer end of the stem 24 is iitted with hand-wheel 26,` the casing 18 is formed with a cylindrical portion 27 which is in communication with the `portion 20. Thepartition wall 21 is formed with a `:torwaidly extending boss 28 which is concentric with the cylindrical portion 27 and is threaded to receive an `oil tube 29l which is bent forwardly through the cylindrical portion 27 and concentric therewith. This oil tube is oi' a dimension considerably lessvthan the inside dimensionsof the cylinder 27 and thus provides a. circumscribing passageway for the steam, mounted upon the forward end of the cylinder 27 is a union 30 which` secures a steamtube or casingl in positionn This casing" agrees in outside yand inside dimensions with the `cylindrical portion` ,27 of themain lcase and circumscribes a pipe running into the yoil pipe294 which extends entirely through the tube 31 and projects out the `i'forwaid end thereof. -The outer end or' the tubel is iitted with a collar ends, one end being in position over-the end of the ltube 31 and the opposite end being positioned over the end ofthe burner jet 34. The jet is formed with an internally threaded portion adapted `to register with the endot' the oil pipe 29 yandto provide a suitable space and connection therewith, the jet is thus detachably secured to both the sleeve 33 and the tube 31. `As shown in Fig. l ofthedrawingsthis jet is preferably iormed with an enlarged oil cavity 35 which extends upwardly and` hasa downwardly extending portion leading on to a` deflecti ing plate 36. -The lower portion of vthe jet is formed ywith a gland. 32 in comn'iunic'a-l tion with thesteam pipe 31, this portion leads upwardly `and will deliverjthe steam against. the under face `of the deilecting plate 36. ThedeflectiilgV plate forms. the division in an openingl in the endlotthe jet and-thus provides a spray' openingfl This collar is threaded at both oi' its y that the baffle plate isv formed Aintegral with a. tip 40 which also forms the openings' 37 and 38, this provides that the tip may be readily removedf-fwlien "desired and the life of the burner prolonged.`

' 1t yis often'rdesirable to provide a burner of for use inconnection with boilers and with -`furnaces of the type known as Peabody fur? iiace s, these furnaces are so designed that vtheflame passes forwardly and upwardly to the tubular boilers and then rearwardly and f'c'lownwardly to the stack. yWhen equipment forsuch furnaces is' desired the casing 18 is used and the pipes 29 and 31 prolonged to any desired lengths; the outer ends of these pipes are fitted with the members shown in Fig. 2 of the drawings. This casing indicated at 41eatends upwardly and "lisa substituteffor the collar 33 previously `f"n'ientio'iied-Vv `Vertical steam passageways are @formed in the casing, an oil passageway 42" and the steam passagewayV 43.

` passageways are separated by a partition wall 44, through which the'eud of the pipe `E29 iis threaded. The partition'wall does not V entend entirely to the top of the casing 4:1 35 butterminates a distance short of the head so that 4'a passageway 4:5 is' provided. Thel passageway a5 vleads the oil downwardly and upon a tip inembereO, similar to one 'used inthe vprecedingr form of the device.

In the form ofthe device shown in Fig. Bof the drawings casing48 is connected to Athe oil pipe 10. Thiscasingis cylindrical and accommodates an oil strainer-a9 throughv whichil may pass to the pipe '29. Cast "1151.r The valvehas a connection 52'with a 'steam' casing through which the pipe Y29` extends and to which the tube 31'is coni easing 18, Aone passingdownwardly to the portion' 2O andthe' other one passing upf' wardly tothe portion 19."` The major por- *tionof the oil will'low through the boss 28v and thentravel along the pipe 29. The' of the steam and, oil'conducting pipes and". "having a discharge orifice formed in its 44buter end, agdeflecting plate supported in "trayel y'ofthis oil will be increased and it `willfloe placed under pressureby 'a by-pas e30/sage ofisteam throug'litheopening 22 in the 'partition wall as regiilated by the valvealong pipe`29` it will Ibe partialy heated fbytha'stea'msurrounding the l"pipe/29 and contained within the 'tubular casing'mem-f These integral with the casingis a vertical eXten- SlOn 50`connectingwith"a regulating,valvey ber 31. The oil will then flow forwardly l and into the cavity 35 from which it will llow onto the baille plate 36. At the same time the steam will pass forwardly and through the` gland to'istrike a'balle plate 36 from the bottom. 5" if' 1t will thus be seen that the oil, of course, will be forced out through the opening 38 and the steam through the opening 37, and

will thereafter Vaporize as it is projecting forwardly. The action will be identical in theform of theidevice shown in Fig. 2 except that the oil will be throwninthe reverse direction romits, original horizontal path oftravelV and may thereafter Y:pass upwardly among the flue pipes of" aboil'er'and then rearwardly through a flue.

lt will thus be seenthat the construction here disclosed insures that an integrally formed casing will 'be provided within which the 'oil and steam may be delivered to suitable vaporizing tips and by which .-the

as it is thus delivered. The burner being constructed in .such a manner as to be decidedly simpler in its construction and op oil may be given pressurefrom the steam-V eration and inexpensive as to manufacturing costs. f

Y While'l 'have shown the preferredfform l of my invention, as now lrnown'to me, it will be understood that various changes' in the combination and vconstruction and arslrilled in the art, without departing from they spirit of the invention as claimed.
